Exhaust issue....

In the last year, I have added a Banks exhaust (2.5" pipe I think), a Kilby gas tank skid, and an OME lift.

After installing the gas tank skid, the exhaust pipe is rattling against the skid and occasionally bumping the shock. I dont think it will really hurt anything, but the rattle is annoying!

I know I could take it to an exhaust shop, not sure how much that would run me, but my guess is $2-300, where they could either bend the existing pipe better, or drop on a smaller one.

I wonder though, is cutting the pipe shorter and just letting the exhaust go under the jeep a bad idea? Conceptually, it sounds simple, but I wonder if theres an aspect I hadnt considered (Im asking this before I cut anything this time).

Thoughts or experience with this or similar issues? Thanks for any help and advice.

The exhaust fumes might be bad if your sitting at idle or going slow, especially with the top down.

My stock exhaust would knock my Rokmen fuel tank skid when I accellerated. I just grabbed the mount abd bent it back a little. Problem solved.

CO2 can be a problem when you shorten exhaust pipes. I won't even run with my rear window open unless both front windows are open as well.

Both good calls. Took it to a different shop and was actually impressed (its been awhile since I said that about a car shop). They just shortened the pipe by about 3", effectively moving the problematic bends forward enough to miss the skid and shock.....

Of course, its still a TJ, and something else is still rattling :-/

....I wonder if it could be the rear track bar on the back of the tank skid, as it seems to be only when the coil on the backend are compressed...
